Python Pandas - 將週期物件作為具有月頻的時間戳返回


若要將週期物件作為具有月頻的時間戳返回,請使用 period.to_timestamp() 方法,並將 freq 引數設為“M”。

首先,匯入所需的庫 −

import pandas as pd

pandas.Period 表示一段時間。建立 Period 物件

period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45)

顯示 Period 物件

print("Period...\n", period)

返回 Period 物件的時間戳表示。我們已透過使用“freq”引數設定頻率。頻率設定為“M”,即每月

print("\nPeriod to Timestamp with monthly (month-end) frequency...\n",
period.to_timestamp(freq='M'))

示例

以下是程式碼

import pandas as pd

# The pandas.Period represents a period of time
# Creating a Period object
period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45)

# display the Period object
print("Period...\n", period)

# Return the Timestamp representation of the Period object
# We have set the frequency using the "freq" parameter
# The frequency is set as 'M' i.e. monthly
print("\nPeriod to Timestamp with monthly (month-end) frequency...\n", period.to_timestamp(freq='M'))

輸出

這將生成以下程式碼

Period...
2021-09-18 17:20:45

Period to Timestamp with monthly (month-end) frequency...
2021-09-30 00:00:00
